l and m are two parallel lines intersected by another pair of parallel lines p and q (see Fig. 7.19). Show that ∆ ABC ≅ ∆ CDA.
l and m are two parallel lines intersected by another pair of parallel lines p and q (see Fig. 7.19). Show that ∆ ABC ≅ ∆ CDA.
Solution and Explanation
In ∆ABC and ∆CDA,
∠BAC = ∠DCA (Alternate interior angles, as p || q)
AC = CA (Common)
∴ ∠BCA = ∠DAC (Alternate interior angles, as l || m)
∴ ∠∆ABC ∆CDA (By ASA congruence rule)
